Detailed Description

C++ wrapper for the Mastodon API.

Since
0.1.0

Typedef Documentation

◆ endpoint_variant

using mastodonpp::endpoint_variant = typedef variant<API::endpoint_type,string_view>

An endpoint. Either API::endpoint_type or std::string_view.

Since
0.1.0

◆ parametermap

using mastodonpp::parametermap = typedef map<string_view, variant<string_view, vector<string_view> >>

std::map of parameters for API calls.

Note that arrays always have to be specified as vectors, even if they have only 1 element. To send a file, use “@file:” followed by the file name as value.

Example:

parametermap parameters
{
{"poll[expires_in]", "86400"},
{"poll[options]", vector<string_view>{"Yes", "No", "Maybe"}},
{"status", "How is the weather?"}
};
Since
0.1.0

◆ parameterpair

using mastodonpp::parameterpair = typedef pair<string_view, variant<string_view, vector<string_view> >>

A single parameter of a parametermap.

Since
0.1.0

Enumeration Type Documentation

◆ http_method

The HTTP method.

Since
0.1.0
41 {
42  GET,
43  POST,
44  PATCH,
45  PUT,
46  DELETE
47 };

Function Documentation

◆ operator<<()

std::ostream& mastodonpp::operator<< ( std::ostream &  out,
const answer_type answer 
)
Since
0.1.0
40 {
41  out << answer.body;
42  return out;
43 }

◆ unescape_html()

string mastodonpp::unescape_html ( string  html)

Replaces HTML entities with UTF-8 characters.

Supports named and numbered entities, decimal and hexadecimal.

Example:

// Will output: 2€ = 2€ = 2€
std::cout << mastodonpp::unescape_html("2&euro; = 2&#8364; = 2&#x20ac;");
Parameters
htmlThe HTML to unescape.
Since
0.4.0
